HMO energy upgrades improve the energy performance certificate (EPC) rating and cut running costs: loft and wall insulation, heating and controls, glazing, ventilation and lighting. In Winchester, a town of around 45,000 people in Hampshire, the work is planned around the HMO rules for England and the council’s written HMO standards. Winchester has a university population, so many shared houses are let to students on yearly tenancies, and summer is the main window for works.
